JAMES G. WENTZEL, OF IVELLSBURG, WEST VIRGINIA.

RAILROAD-RAIL.-

SPECIFICATION forming part of Letters Patent No. 7 31 ,253, dated June16, 190 3.

Application filed March 3,1903.

Wheel-flange with the rail when rounding. a

curve.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate like parts throughout both views, inwhich- Figure 1 is a top plan view of a portion of a curve-railconstructed in accordance with my invention. Fig. 2 is a cross-sectionalview of the rail in perspective.

In accordance with my invention the tread l of the rail, the web 2, andbase 3 are of the ordinary construction. In the side of the tread to beengaged by the flange of the wheel 1 form a groove l, opening out at theside of the rail, but the said opening at the side being of less Widththan the largest diameter of the groove. This groove has placed thereina series or plurality of antifriction-bearings 5, contacting with eachother and held in position by the overhanging edges of the grooved wall,the antifriction bearings or balls being inserted into the rail from theend thereof.

Serial No- 145,890. (No model.)

As the flange of the car-wheel engages with these balls instead ofdirect with the side of the rail-tread by reason of the balls projectingbeyond the side of" the tread, the friction of the wheel in rounding acurve of the track may be materially reduced.

In the practice of the invention it will be noted that various slightchanges may be made in the details of construction without departingfrom the general spirit of the invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A device-of the type set forth comprising a rail having a web andbase, a tread carried by the said web having a circular recess formedtherein, the sides of the tread of said rail being brought together topartially close said recess, and balls carried in the recess and heldtherein by the sides of the tread, substantially as described.

2. A device of the character described, comprising in combination with arail having a base and web, a tread formed integral with said web,alongitudinal circular recess formed in one side of said tread, saidrecess-opening at the ends of the rail, balls of smaller diameter thanthe recess seated therein, and adapted to extend partially beyond thesame to form a contact for wheels, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.
